As well as the Friends of Blair Peach Committee and the Anti-Nazi league, one of the main organisations keeping pressure on the Home Office to concede an inquiry was the Committee founded by the National Council of Civil Liberties.

Chaired by Michael Dummett and with members including Joan Lestor MP, Patricia Hewitt General Secretary of the NCCL, Paul O’Higgins, an academic lawyer at Cambridge, and the philosopher and activist Stuart Hall, the NCCL report would eventually conclude:

“There is reason to believe that Blair Peach was killed by an SPG officer, and no evidence to suggest that he was killed by anyone else. It is a matter for astonishment that the police investigation in his killing has resulted in no criminal or disciplinary proceedings.”
